The problem of students' heavy academic burden is no longer a problem of education itself. The government has issued countless documents for governance many times, but the effect is very limited and getting worse. Education is a systematic project which includes at least three parts: family, school and social education. The success of education is the result of the comprehensive function of these three major educations; If there is something wrong with education, it is natural to analyze and find the reasons from these three aspects. Only in this way can the symptoms be cured. This paper discusses the reasons from these three aspects and puts forward its own solutions. The main manifestation of students' heavy academic burden is "two more and three less" in time. More than two means more school time and more passive learning time; "Three Less" means less time for rest and sleep, less time for physical exercise and less time for active study. From the weight point of view, the main performance is that the schoolbag is too heavy. At present, students have too many subjects to learn, and since the implementation of the new curriculum, the textbooks of various subjects have flooded, resulting in the rapid expansion of students' schoolbags, so that various high-tech schoolbags emerge one after another. From the perspective of curriculum setting, it is mainly manifested in the emphasis on liberal arts and the imbalance of curriculum configuration. At present, the curriculum of primary and secondary schools, especially junior high schools, is mainly liberal arts. Chongqing junior high school entrance examination, the total score of mathematics, physics and chemistry is 300, and the total score of Chinese, English, physics, chemistry, history and history is 400, excluding sports. Especially English, the new curriculum has been extended to primary schools. At present, "quality English" is practiced in primary schools, and junior high schools, senior high schools and universities have become "exam-oriented English". English boring rote learning has become a nightmare for many students, especially boys, and has become a major focus of students' heavy academic burden.
